GAGE FOR CLARPENTRY.

SPECIFICATION forming part of Letters Patent No. 447,60 4, dated March 3, 1891.

Application filed October 16, 1890. Serial No. 368,336. (No model.)

To all whom it may concern:

Be it known that I, MATTHEW Osman, a citizen of the United States, residing at Ross township, in the county of Alleghenyand State of Pennsylvania, have invented or dis covered certain new and useful Improvements in Gages, of which improvement the following is a specification.

The invention described herein relates to certain improvements in gages for carpentry and like work, and has for its object a construction whereby two or more lines or marks may be simultaneously formed parallel with an edge or previously-formed guide.

In general terms the invention consists in the construction and combination of mechanical devices or elements, all as more fullyhereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure l is a perspective view of my improved gage. Fig. 2 is a plan view of the same, illustrating its manner of operation, and Fig. 3 is a sectional detail view of one of the pencil-holders.

Vhile the gage hereinafter described is more especially applicable for use in shingling houses and other like operations, it is also equally well adapted for other uses.

The fence or guide block 1, adapted to bear against the lower edge of a row of shingles .or the edge of a board or other article,is preferably provided on its operative edge with a groove for engaging the corner of the lower edges of the shingles or the corner along one side of the board or other article, as shown in Fig. 1. v A

The beam 2 is adjustably secured by means of a set-screw 3 in a post or standardet on the fence, and on the beam are mounted blocks 5, movable along such beam and held in any desired position with relation to the fence and each other by set-screws 6. Blocks 7, provided with suitable means for holding pencils or other markers S-as, for example, the slots 9 and set-screws 10 are connected by springs 11 to the blocks 5, in order that a pencil or marker may be yieldingly held against the surface to be marked and permitted to rise up over any irregularity on said surface, thereby avoiding all liability of breaking such marker or interrupting the movement of the gage. On the outer end of the beam is mounted a disk 12, provided with spurs adapted to engage the surface to be marked. It will be observed byreference to Fig. 2 that the beam 2 is arranged at angle less than a right angle to the guiding-edge of the fence, and that as the axis of the beam and disk coincide the disk will tend during the movement of the gage to move away from the edge against which the fence bears, and thereby hold said fence firmly against the guide-edge of the board or row of shingles. The same function can be effected by arranging the beam 2 at right angles to the edge of the fence and then bending the portion of the beam on which the disk is mounted at an angle to the main part of the beam. This angular arrangement of the side of the disk and the edge of the fence is of especial advantage when the gage is employed on sloping roofs, the gage being thus automatically held up to its proper position. In addition to holding the gage in proper position, the disk with its spurs will serve to mark a third or fourth line, dependent upon the number of holding-blocks on the beam.

For convenience of manipulation the gage is provided with a handle 13, preferably secured to the beam by means of a set-screw 14; but the handle may be attached to the fence, if desired.

I claim herein as my invention- 1. A gage having, in combination, a fence, a beam adj ustably attached thereto, and one or more yielding. holders for the pencil or marker adj ustably attached to the beam, substantially as set forth.

2. A gage having, in combination, a fence, a beam adjustably attached thereto, and a disk provided with spurs mounted on the beam with its axis at an angle less than a right angle to the guiding-edge of the fence, substantially as set forth.

3. A gage having, in combination, a fence, a beam adj ustably attached to the fence, one or more blocks adjustably mounted on the beam, and one or more blocks provided with means for holding pencils or markers and having a yielding connection to the adjustable blocks on the beam,substantially as set forth.

4. A gage having, in combination, a fence, a beam adjustably attached to the fence at an angle less than a right angle to the guideedge thereof, one or more yielding holders for the pencil or marker adj nstably mounted on the beam, and a disk provided with spurs loosely mounted 011 the outer end of the beam, substantially as set forth.

In testimony whereof I have hereunto set my hand.
